### Divide by zero

Do you ever think there would be a second imaginary number?  A one about x/0?  There could be one, since √-1 was once thought to be impossible.

### Re: Divide by zero

Hi calculator;

One problem with x / 0 is that when we have

we can multiply that 3 on both sides and it makes sense.
6 does equal 2 * 3. But since we agree that 0 x anything = 0 let's see what happens. Supposing we say

we multiply by 0 on both sides and get the contradictory statement that 6 = n * 0 when we already know that anything times 0 is 0.

So, I would say you will never see that definition changed.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Those arithmetic are clearly not working with x/0 but that does not stop you from calling it an imaginary number.

It is undefined. Imaginary number was a term used for a complex number.
